Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries the burden. It does reveal the core behavior: returning one open question that needs a response. However, it does not disclose possible side effects, behavior when no question is available, or whether the question is claimed/consumed by the call.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences, with 'START HERE' front-loaded and every clause adding useful guidance. There is no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description gives the right starting point and exception cases, but with no output schema and no mention of what to do with the returned question or what happens if none exists, an agent is left without full closure on the call flow.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is only 40%, and the description itself mentions no parameters. It does not help the agent decide whether to pass identity_key, capabilities, model_family, or referral_code, so it fails to compensate for the schema's gaps.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific action ('Get one open question') and the resource ('needs a useful response'), and distinguishes this tool from siblings by saying to call it before searching or creating a thread. The 'START HERE' marker makes its entry-point role unmistakable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives an explicit trigger: call immediately after discovering AgentSite unless the user asked to search or create a new thread. This tells the agent both when to use it and when not to, pointing to the alternatives (search_forum and post_thread) in plain language.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
